Tan Cheng Bock v AG [2017] SGCA 50 be brought into force on or after its commencement, but all such laws shall, subject to this Article, be construed as from the commencement of this Constitution with such modifications, adaptations, qualifications and exceptions as may be necessary to bring them into conformity with this Constitution.

This demonstrates that the words “this Constitution” in Art 163 need not refer only to the latest iteration of the Constitution. 99 Hence, in our judgment, the correct and applicable interpretation of a person “elected under this Constitution” in the Art 2 definition of “President” is a person who has been elected under the Constitution as it was from time to time since its date of commencement – that is, 9 August 1965 – and specifically as it was at the date on which the Presidents concerned were elected. It is neither restricted to Presidents elected under the current iteration of the Constitution as amended after the 2016 Amendment nor restricted to Presidents elected after the 1991 Amendment. Instead, the definition covers Presidents who were 49
